Liftmaster MYQ Internet gateway

[koen_dc]

Hello,
I just bought the MYQ INTERNET GATEWAY 828EV.
I was able to install and connect the gateway to my garage motor unit (model LM80 EVS).

However i'm only able to open the garage.
when the garage is already open, i'm unable to close the garage via the app or website.
(getting error like: device not responding, please try again later)

anyone can help me out here? :-)

Hi,
To be able to remotely close the door through the app you require photocells to be installed. They are the 771E photocells and Liftmaster/Chamberlain have done this so you are unable to close the door if there is an obstruction blocking the photocell beam.
